			====='''Rendering Image Sequence from UE'''=====
			* For those who wants to render from UE straight an image sequence here are some tips:
			** After creating a sequence with camera movement/keyframes, you directly render via '''Movie Scene Capture (Legacy)'''. [https://www.youtube.com/watch?v=CW8hDvJOwGM Here] is simple step by step tutorials on this.
			** However, I have noticed that sometimes camera is stuck at 0, 0, 0 on the render eventhough you animated the camera. In this case you need to bring to your sequencer from +Add: '''Camera Cut Track''' and attach the '''Cine Camera Actor''' that you are using. Ensure that your sequencer wheel is set to frame 0 at the beginning of your timeline.
			** And those who wants to have more high quality and accurate renders, you have to use '''Movie Render Queue''' (needs to be enabled from plugin).

	The Copernicus environment, also known as COP, is a 2D and 3D GPU image processing framework that enables real-time image manipulation within a 3D space. This framework consists of COP nodes, which provide a unique node body with a preview thumbnail, and can be wired together to control the flow of layer and geometry data. COP nodes fully interoperate with Surface Operators (SOPs), allowing seamless integration between 2D and 3D workflows, and can export results as images or volumes. The default image space ranges from -1 to 1, preserving the pixel aspect ratio, and texture space ranges from 0 to 1 across the data window and buffer space, useful for mapping textures. As of Houdini 20.5, Copernicus nodes are recommended instead of Compositing nodes, with the Compositing network now designated as COP Network - Old.
